Since the beginning of this year, Kalshi has marked more than 400 suspicious transactions, more than double the number of investigations carried out by the platform throughout last year. Similarly, the volume of transactions marked as suspicious by Polymarket has increased significantly this year, but no details have been disclosed.
However, identifying the negative actors on the predictive platform may be difficult. According to Joseph Grundferst, Professor at Stanford University Law School and former member of the United States Securities and Exchange Commission, “It is usually easier to identify persons who have significant, non-public information and engage in illicit transactions in insider trading. However, it is often very difficult, if not impossible, to collect similar data in predictive markets.”
The increase in suspicious transactions was accompanied by a surge in transactions between Kalshi and Polymarket. Kalshi stated in early May that its annualized trade volume had more than tripled over the past six months to $178 billion. According to Dune Analytics, monthly transactions on the Polymarket offshore exchange and the United States platform reached approximately $10.3 billion in April, compared to $3.8 billion in the same period last year.
The enhanced scrutiny by regulators is accompanied by enhanced protection by the trading platform itself. Predicting market regulation is now the focus of a competition between the Commission on Commodity Futures Trading (CFTC) and the relevant agencies, which believes that the forecast market should be regulated like the derivatives market. Nevertheless, the experts indicated that the increase in tradables showed that the positive returns of successful bets allowed investors to take on the risks involved.
Consumer interest in the predictive platform has boosted their valuation. Kalshi had recently completed a $1 billion round of financing, which had brought its valuation to $22 billion, an increase of more than 10 times over one year. It was also revealed by an informed source that Polymarket was negotiating a new round of financing with a value of $15 billion, following the delay in the United States exchange earlier in the year.
According to Reuters, investors are increasingly turning to forecast markets before critical buying and selling decisions are made, as they have become accurate indicators of economic policy announcements or election outcomes, even more than traditional polls.
Kalshi was founded in 2018 by Tarek Mansour and Luana Lopes Lara, classmates of MIT. Pollymarket was launched by Shayne Coplan in the 2020 epidemic, initially as a crowd-sourced forecasting experiment, and has evolved over the past few years into a mature event contract exchange that generates multi-billion-dollar transactions per month.
However, recent high-profile insider trading cases have led to more rigorous scrutiny of these platforms. The Chairman of the CTC, Michael Selig, recently indicated that the agency would actively prosecute insider trading. In March, the CTC began to develop regulations for predicting markets.
In response to a review by legislators, both Kalshi and Polymarket have recently updated the rules, stressing that certain types of bets (including those made using classified information and illegal insider information) will not be allowed to take place on their platforms. After public scrutiny, Polymarket recently removed some war-related bets and contracts.
